PN Junction and Contact Potential Explained | AKTU & RGPV Electronics | GATE ECE Preparation

n this video, we’ll understand the PN Junction Diode — how it is formed, what happens at the junction, and the concept of Contact Potential (Built-in Potential).
This lecture is specially designed for AKTU, RGPV, and GATE ECE students to build a strong conceptual foundation in Semiconductor Physics.

What you’ll learn:

Formation of PN Junction

Diffusion and Drift Mechanisms

Contact (Built-in) Potential Explanation

Energy Band Diagram of PN Junction

Important Points for AKTU & RGPV Exams

📘 Useful for:

B.Tech & Diploma ECE Students

GATE ECE Aspirants

AKTU / RGPV University Exams
